Hello vlado30,
Do not worry. Some things are not subject to correction. The problem is that the faulty controller of the SD card reader is a part of the CPU. You must understand that to repair your card reader, you need to replace the motherboard or CPU, at least.
You can not do this at all because such repairs would be an unreasonable waste of your money. Therefore, accept this loss and be happy. Let this remain the biggest loss in your life.
